Fault diagnosis of co2 laser marking machine, how to deal with leakage?

CO2 laser marking machine uses a laser beam to mark permanent marks on the surface of various substances. The effect of marking is to expose the deep material through the evaporation of the surface material, or to 'engrave' traces through the physical changes of the surface material caused by light energy, or to burn off part of the material through light energy to reveal the desired etching pattern. , text, barcodes and other graphics. The following is the treatment method for the fault of the marking machine.

Fault diagnosis of laser marking machine, how to deal with leakage situation?

First, the laser tube bright voltmeter has indications

1. The laser power drops, and the fault is often caused by the aging of the laser tube

Inspection method: check the voltage regulator with the voltage gear of a multimeter, and check the working voltage of the laser tube with a high voltage meter

Treatment Method: Replace the aging laser tube and replace the damaged components.

2. Irregular light output, the light guide joint is hot,

mainly because the light guide joint is loose and the laser tube is not installed Positive inspection method: same light correction

Treatment method: replace or adjust the light guide section, and correct the light path.

Second, the laser tube does not light up

1. The voltmeter has Indication, the fault is usually caused by the open circuit of the power supply line and the poor contact of the foot switch or manual switch

Check method: measure with a multimeter

Remedy: Repair or replace.

2. The laser power decreases,

This fault is often caused by the aging of the laser tube

Inspection method: Check the voltage regulator with the voltage gear of a multimeter, and check the working voltage of the laser tube with a high voltage meter

Treatment method: replace the aging laser tube and exchange damaged components.

3. Continuous burning of the fuse, the fault is due to a short circuit in the machine and serious dirt in the machine

Check Method: Check the wires step by step, mostly because there is a short circuit in the high voltage part.

Treatment method: Repair the short circuit and remove the dirt.

4. There is no indication on the voltmeter, the fuse is usually broken, or the circuit is open

< /p>

Inspection method: measure with a multimeter

Treatment method: replace the fuse, or connect the circuit.

5. There is a discharge sound or arc light in the machine,

There is a discharge sound or arc light in the machine. There is dust, standing water or air humidity is too high and there is corrosive gas

Inspection method: observe the discharge point in the dark

Treatment method: remove dust, accumulated water, etc., and replace the working environment.
